Getting to Know the Layers on Solar Panels and Their Functions

In the era of transition to renewable energy, solar panels are increasingly popular as a solution to meet environmentally friendly electricity needs. However, many are still unfamiliar with the components contained in solar panels and their functions.

In fact, the components of the Solar Panel are a unit of the device so that it can function properly. In order to become an applicable tool, other parts of the solar panel are needed. Here are some layers of the solar panel and their functions:

1. Junction Box

Junction box is a safety box used for electrical circuits or electrical cable connections. The use of a junction box aims to ensure that the cable or network connection on the cable is not disturbed by activity and is not dangerous.

2. Backsheet

The back layer of the solar panel that serves to protect the photovoltaic cells from moisture and environmental impacts. This layer also helps maintain the structural integrity of the panel.

3. Encapsulation Materials

It is a material that protects cells from direct contact with the environment and mechanical forces that can damage thin cells.

4. Sel Fotovoltaik

It is the main component of a photovoltaic module. This cell is made of a semi-conductor material that captures sunlight and converts it into electricity. The cells are connected in series to obtain a higher total voltage through the busbar wire. The material used for photovoltaic cells is generally silicon, such as polycrystalline and monocrystalline.

5. Encapsulation or Lamination

Layer between photovoltaic cells and protective glass. Lamination is used to prevent mechanical damage to photovoltaic cells and isolate the voltage from photovoltaic cells to other parts of the module. Usually the laminate sheet uses ethylene-vinyl acetate (EVA) material.

6. Tempered Glass

Protecting photovoltaic cells from the environment and ensuring the rigidity of the panel. Due to this function, protective glass takes up the highest proportion of the total weight of the photovoltaic module.

7. Frame

Usually made of Anodized Aluminum to prevent corrosion. The frame is installed at the end of the manufacturing process, so it has a function to ensure the strength of the panel.

Therefore, it can be concluded that Solar Panels are a combination of various components that work together to produce electrical energy from sunlight. By understanding the function of each component, we can better appreciate this technology and its potential to reduce dependence on fossil fuels. The application of solar panels is not only economically beneficial, but also makes a positive contribution to the environment.

Together with SEI, let's move towards renewable energy!
